MAINTENANCE, CLEANING, AND STORAGE
Before each use, a respirator must be carefully inspected to assure that it is complete and in good
operating condition. A respirator that is not complete must not be used until such time as it is completely
repaired. Only approved parts should be used as replacements and to make repairs. Using other parts
will void the NIOSH approval for the respirator and may result in bodily injury or death.
The hood and its components used by an individual should be inspected and, if possible, cleaned and
sanitized after each day of use.
The 9910D and 9910DS series hoods are intended to be a disposable type hood. If the hood is damaged,
torn or contaminated in any way that would affect its performance or cause any possible hazard to the
user it should be disposed of properly.
INSPECTION
Inspect the hood for damage such as tears or rips.
Inspect the lens for scratches, cracks, creases, dents or any other type of damage. Inspect all sewn
seams.
Inspect the breathing tube for signs for cracks, holes, kinks, or other damage, as well as flaking or
deterioration of the foam baffle inside the breathing tube.
Inspect the fittings for proper attachment.
Inspect belt for unusual wear such as cuts, tears, fraying, or damaged hooks or buckles.
